  1. I was wondering why there are very few custom frame builders working in Alu, Ti or carbon.

    30 Years ago almost everyone rode steel frames and many cities would have several frames builders
    turning out custom and off the peg frames for racing and touring cyclists.

    There were very few mass produced top quality frames, the process did not seam to scale well. On the
    other hand the capital costs to equip a workshop to produce one or two frames a week were on the
    scale of a couple of month wages.

    I can see that mass produced Alu and Carbon frames have captured the top end of the market, but that
    few custom builders have moved into these materials.

    Is this due to inertia and lack of foresight by the builders? Are the large capital costs involved?
    Is it mainly due to being unable to compete with offshore wage levels?

    The internet certainly didn't help the local custom framebuilder. Just a few great full time frame
    builders can serve a much larger population these days.

    You overestimate the number of frames a builder can rasonably make. Richard Sachs doesn't make more
    frames now per year than he did 5 years ago-well, maybe a couple. there's a limit of how many frmes
    a person can make a year so now the internet exposes more builders to more potential customers. I
    used to build in LA before I moved but I had customers in New Jersey-all through the internet. It's
    a great thing. Phil Brown

    Techniques for brazing or welding steel are much easier to master (and equip for) than reliably
    welding aluminum. Titanium is reportedly at least a full quantum level more difficult than that.
    (This is from an aerospace engineer who has to design for the stuff.) Carbon fiber is an entirely
    different kind of process. To be competitive or even competent in those materials is probably beyond
    the level of expertise that a lot of the older steel frame builders could have handled; the current
    ones may just prefer to stay with what is reliable and known.

    It may be that more custom builders would have made the transition to new materials if there hadn't
    been as much market pressure from the mass-produced units, though. It's probably a combination of
    effects, with each case being a bit different.

    makes it a tough sell when compared to Moots, Seven, etc.

    Carbon is just plain expensive(altho Calfee is available in custom). As for aluminum, tough to

    Also I think most well established and knowledgable frame builders realize that steel offers the

    The actual welding of the frame isn't THAT much more difficult, but setting up the necessary
    equipment to do it IS. The most important difference is that you have to be VERY careful to prevent
    air from contaminating the weld - just a few molecules of the stuff can affect a weld. And it IS
    more difficult to cut and machine (it's hell on cutting tools).

    If you want "custom" carbon, you have a couple of choices, Calfee and Parlee. Calfee has been in
    business longer, but I understand Parlee frames are very nice. I also understand its possible to get
    a custom Colnago, but that will probably take alot more time and $$$.

    What's that? The extra weight of lugged construction? The lack of natural corrosion resistance? The
    general inability to build a frame as light as other materials? The fabulous tales of repairability?

    Steel isn't as terrible a material as I jokingly make out here. Indeed, the irony is that my
    mountain bike is welded steel (old Kona Kilauea), and my road bike is lugged steel (old low-end
    Pinarello). I bought them because they were good deals; the used market is fairly thick with cheap
    steel bikes because they have mostly fallen out of favour (bikes with vintage value excepted).

    Compared to aluminum, steel used to be cheaper. But that has changed a lot, to the point that
    materials costs don't factor into retail frame prices between them; you can get cheap or expensive
    frames in either material, sometimes from the same company.

    The other tale oft told is that steel frames are repairable, aluminum ones are not. Discounting the
    fact that the cost of repairing a frame makes this folly on all but the most costly or sentimental
    frames, aluminum can now be properly repaired and treated too:

    pyrobike.compyrobike.com

    Beyond those considerations, you are left with hand-waving arguments about ride quality, rhyming
    slogans, magnetism, and the aesthetics of lugged construction. If you really like lugs, then steel
    is real, but I am not so sentimental.

    What I like best about my steel Pinarello (besides the price and the pretty chromed chainstay) is
    that finishing well in my crit races (personal-best of 5th place last time, woo hoo) makes the

    I actually think its easier to distinguish yourself in steel than in other materials. an aluminum

    new shapes, use custom bridges, etc., to create a market presence for himself. its much more

    I respectfully disagree with that assertion. Not sure to what that aerospace engineer was referring,
    but titanium is not at all difficult to weld and is similar to steel(that is, using the GTAW
    process). Aluminum requires an AC arc which transfers a lot of heat to the tungsten and the torch,
    and aluminum gives little visual warning as it changes from solid to liquid.

    The only real complication with Ti is the absolute requirement for an oxygen-free environment on
    both sides of the weld, necessitating back purging with an inert gas. Ti can be more difficult to
    machine or otherwise work the pieces into the desired shape and is far more ixpensive than either
    steel or AL.

    I respectfully disagree with that assertion. Not sure to what that aerospace engineer was
    referring,

    A relatively simple part may require the use of an inert gas chamber with gloves. or an O2-free
    *room* with full breathing gear, due to the length of the weld and the impossibility or
    impracticality of merely flooding the area of the weld and the back of the seam.

    process).

    By comparison to the minimal techniques required for satisfactorily welding ordinary steel, that's
    quite a bit more involved. Yes, the same techniques that work for titanium are also effective with
    steel, but the reverse is not true. Good welds can be done in steel with relatively simple gear; a
    wirefeed inert gas setup can make a better weld than an oxy-acetylene torch, but *none* of the gear
    needed for Ti is required for a brazed and gusseted steel frame. The brazing technique, however, is
    useless for Ti.

    Aluminum requires an AC arc which transfers a lot of heat to the tungsten and the torch, and

    I'm too familiar with this. When replacing valve seats in aircraft engine cylinders, the aluminum
    head may have to be heated to within a hair's breadth of where the cooling fins begin melting. (I
    miss working on those, sometimes; I haven't done one in over 20 years, now.)

    An oxygen-free environment is nice when welding steel, but not mandatory, and only in exotic
    applications would a completely O2-free work area be called for; thus, a framebuilder (or other
    fabricator) working with steel often, if not usually, needs less skill and less complex equipment
    than one working with Ti. And, as you noted, Al has characteristics all its own. (On the other hand,
    from several sources, I have heard that once you're used to it, welding Al is less of a bother than
    a lot of steel. Not so with Ti, according to the welder in the family, although he says that the
    stone [censored] is stainless of unknown alloy...which he works with regularly, since he fabricates and
    repairs custom restaurant equipment.)

    bottles is full compared to empty?

    Probably not, but it's a close-run thing to keep up on the climb some races.

    Rigged and ready to run (bell, but no water bottles), the Pinarello is 22 pounds according to my
    bathroom scale.

    I don't ride another road bike to compare this one to, but it doesn't feel heavy when I'm racing.
    Then again, the triathlete beside me at the finish last time noted that his new (non-aero
    crit-style) wheels felt "more responsive" than his usual (presumably aero) wheels. I don't know.
    Maybe he was sensitive enough to notice.

    I like the Pinarello because it represents my whole approach to racing, which is to focus on the
    things that make me faster. I'm sitting beside guys with sweet $3000 bicycles, in full Euro-team
    replica kit. That's cool for them, because I'm sure they enjoy the aesthetics and it probably does
    help them get up for the racing.

    Meanwhile, I have my wacky pastiche-bike with a carbon fibre Trek fork (it was cheap, and the stock
    fork was rusting) and a single Sora 8v shifter setup (because right-side STI does make a difference
    in crit racing), and my kit consists of black shorts and either my plain red jersey or my plain
    beige jersey. I like the DIY style of it all, (which is to say, my bike budget is low), and I've
    been careful to be cheap where cheap doesn't make me slower ($30 Bell Paradox helmet instead of a
    sweet Giro Pneumo in Italia tri-colour). I sit in to punish the over-eager triathletes, and I let my
    legs and my cornering skills do the talking (mostly they say, "this hurts!"😉

    The real point is that I could probably force a pound off of this bike with really judicious
    component replacement, but it was a lot easier to just lose 10 pounds off me this Summer, and
    there's another 10 that I have my eye on.

    I salute your delight in the absurd under intense situations! For you, I will be sure to ring the
    bell during Tuesday's race, the last of the season.

    That depends on the repair. Replacing main tubes is probably uneconomical, but I bet many repairs
    are smaller things like bent dropouts. There steel has an advantage. And repair-by-replacing an
    entire frame is a PITA even if the frame is free. I wouldn't necessarily choose a material for these
    reasons though. BTW, heaven help us all if Campagmano decide to change the rear spacing again.

    To the OP: Nonferrous materials can involve larger capital costs, like welding equipment and heat
    treatment for aluminum, bladder molding and tons of engineering for carbon, etc. There are smaller
    builders who build in aluminum and titanium, but not as many. BTW, 30 years ago my guess is that the

    Here we go-aluminum corrodes quite well and I have an 18 year old Ciocc w/o any corrosion on it
    or in it.

    I don't think most frames succumb to corrosion, but when I hear people extol the virtues of steel,
    they generally refrain from mentioning its vices, however minor.

    Quoted message said:

    ryan<< The general inability to build a frame as light as other materials? >><BR><BR>

    Horseshit. My steel builder builds steel in the 3.2 to 3.5 pound range all the time, just like
    most aluminum and mid range ti. If ya want a light frameset, sure you can get one, for a lot more
    $$($2900 for a Calfee Dragonfly), or in Ti-check out the prices of the 1 kilo ti Litespeed
    framesets or perhaps an aluminum/scamdium 1 kilo framesets that are $2500 and may last one
    season...

    Well, I daresay a 3.2-3.5 lb. steel frame sounds pretty deep into the stupid-light zone for that
    material. Meanwhile, a Ti frame (or Al, or carbon fibre) at that same weight is arguably overbuilt,
    and not too expensive:

    habcycles.comroad.html

    3.-3.7 lbs. in sizes from 50-64 cm. $695.

    (I'm not particularly picking Mark's bikes for any reason other than the nice chart with all the
    weights right there; I suspect his bikes are on the cheap and heavy side of Ti frames, not that
    there's anything wrong with that.)

    Folly is right. You need to read some info about how these are 'repaired' and how reliable the
    repair is.

    Well, that particular company comes from an aviation repair background, and tests for alloy type and
    heat-treats their work afterwards. I'm not sure what the folly is, given that post-weld heat
    treatment is the one thing that most welding shops can't do to an Al frame.

    Quoted message said:

    Ryan<< If you really like lugs, then steel is real, but I am not so sentimental. >><BR><BR>

    There you go again...never mentioned lugs...

    Sure. And welded steel frames (heck, even lugged steel frames) are very good. As I mentioned, I
    have two steel bikes: a welded Kona hardtail, and a lugged Pinarello. I race both at a low level
    (beer league/Cat 5), and the magnetic nature of the frames is not what holds me back from
    greater glory 🙂.

    As I mentioned either here or in another thread, I think steel frames are an especially good bargain
    on the used market because their cachet (collectibles excepted) has sunk faster than their
    functionality.

    But in the new frame or bike market, I don't see a lot of market territory that steel frames have
    covered well. On the simple two axes of price and weight, there are light steel frames that cost
    more than non-Fe frames of the same weight, and there are heavy steel frames that weigh more than
    non-Fe frames of the same cost. At the extreme ends of the market, there are (as you mention above)
    stupidlight frames that get into the 1 kg range, and a Trek OCLV (a bike I have never heard
    described as fragile or underbuilt) frame weighs about 2.3-2.4 lbs, a weight no steel frame is
    likely to approach at any price, and OCLV frames are not outrageously expensive by the rarefied
    standards of high-end frame pricing.

    As for reliability, a frame in any common material should have a service life longer than any
    component attached to the frame. 20 years of regular riding, at the bare minimum. I would just
    expect that of any normal bike, and have no reason to doubt that in any material, an unforced
    road-frame failure sooner than that would indicate a failure in design or manufacture. There are
    specific stupid-light frames (in steel and aluminum, though demand for the former is minimal now)
    designed outside these parameters, but they come with weight limits and bogus warranties to go along
    with their astonishing lightness, and the non-sponsored rider should be forewarned.

    Only in the realm of the cheapest road bikes does steel usually have a cost advantage over the
    next-cheapest material, which is usually aluminum.

    This is quibbling over trifles: what I was trying to say was not that steel frames were a waste of
    money. At worst, they are a small waste of money, and at best they have some specific attributes
    that make them interesting. One of those (I hesitate to bring it up) is that some lugged steel
    bikes are very pretty. Another is that if you are in dire straits and absolutely have to bend your
    frame into another shape (say, because it got bent into the wrong shape, or you need to cold-set
    your rear triangle to a new spread), then steel is real (and if you have to heat-treat it, steel
    will anneal 🙂.

    But most riders will probably find a better value off-the-rack in Al frames than Fe frames. And as
    long as Habanero keeps selling custom Ti for $995, it will be hard for custom steel builders to
    match the price, much less the weight.

    That said, a local steel builder may simply offer a better, prettier frame with better service and
    faster turnaround. They may even be able to beat the price (though rarely the weight) of most other
    custom makers. This is partly because steel lends itself to easy manufacture with relatively
    inexpensive equipment, and partly because there are a lot of people able to custom-make steel
    frames, leading to a buyer's market.

    So I'm curious: although you rebutted some of my knocks against steel, what do you see as the
    advantages of steel that make it preferable to other materials (which is to say, mainly to
    aluminum). Would you make your arguments only when referring to custom builds, or would you say that
    even in the off-the-rack market steel is generally preferable to other materials?

    Sheesh, it seems like I've been picking on you a lot this week. Maybe it's time to go for a ride.

    My skin is a lot thicker than that. I have been slammed by the likes of Jobst, after-all...

    Probably because you attribute ride characteristics to Ti frames.

    BTW, carbon fibre is easy to repair. Nobody likes to think about it, but carbon fibre is fibreglass
    boat technology with a lighter-weight matting. I believe the major reason nobody considers
    repairing carbon fibre is because Trek's frame warranty is so good. Don't know if the same goes for
    Calfee, et al.

    A broken carbon frame contains a world of mystery as to whether it's been compromised in other than
    the obvious place(s). In the aerospace world, a patched composite component would not be used for
    this reason.

    Boats usually sink gradually, though. :-)

    Why don't you read the post. Didn't mention 'lugs', you did. BTW, I have a 3.6 pound lugged steel
    frameset. Weigh a stadard aluminum frameset lately?? How about the low end Seven ti??

    Ryan<< The lack of natural corrosion resistance? >><BR><BR>

    Here we go-aluminum corrodes quite well and I have an 18 year old Ciocc w/o any corrosion on it
    or in it.

    ryan<< The general inability to build a frame as light as other materials? >><BR><BR>

    Horseshit. My steel builder builds steel in the 3.2 to 3.5 pound range all the time, just like
    most aluminum and mid range ti. If ya want a light frameset, sure you can get one, for a lot more
    $$($2900 for a Calfee Dragonfly), or in Ti-check out the prices of the 1 kilo ti Litespeed
    framesets or perhaps an aluminum/scamdium 1 kilo framesets that are $2500 and may last one
    season...

    COMBINATION of things that make a good frameset.

    Well that depends on what the purpose is. I think for the non-racer, steel is a very nice choice.
    Especially given all the perfectly good used 5.5-6 lb steel frame/forks on the market. One should
    expect to pay only $50-100 for these. I train on a 21.5 lb steel bike. But there's no way it is
    going to compete when that "COMBINATION" you talk about is slanted heavily towards weight and
    possibly lateral/torsional stiffness. I have 5 steel bikes. I bought a $1900 frame/fork CF finally
    because it is <3.0 lbs. A new steel frame/fork would likely cost a similar amount and it would weigh
    in at about a lb more (at least). Being able to "feel" the lb or two is irrelevent. People get
    blisters because they didn't "feel" it soon enough. I can stomp on my light CF frame in a sprint and
    it seems quite rigid, for whatever worth this sort of subjectivity has. Granted, it is hard to
    separate what is twisting in a sprint, but the CF bike has 225g Al handlebars. I do wonder how a 3.2
    lb steel frame would feel, all other things equal. I don't like that twisting feeling in sprints.

    Steel is still a very good material, even if it is out of favor currently. But for racing, I think
    the "performance factor" gets much more weight when your "COMBINATION" is summed up. There, the edge
    goes to other materials, particularly CF. For non-racing, steel is a great choice, and it isn't like
    one could not race with it. I did many flat crits last year on my old steel 22 lb crit beast (more
    mass to accelerate in sprints). For climbing events, I'll certainly go with the lightest I can
    afford: steel isn't happening for that. I'm not going to work hard driving the weight on my body
    down to a 21.0 BMI only to add it back on the bike frame.

    I didn't have a bell, but I did turn on my rear blinker light for the sprint signs.

    If ya want to race, get a throw away aluminum frameset, save even more wierght, get a stiff, light
    racing frameset, not CF.

    No thanks.

    OBTW-$1900 for a steel frameset and fork is way too much...

    It isn't hard to get up into the $1200-1300 range. The last bit of margin is usually the most
    expensive, and this case is no different. It ends up as a personal choice as to whether it is
    "worth it."

    On a test machine, i think it would fell a lot alike. A light steel frameset isn't all squishy.

    No point in going further with this. Measurements would sort it out. Conceptually, CF would seem to
    have the advantage over steel. The issue is probably more magnitude than anything: is it enough to
    care about?

    Most 'racers' are more about equipment than performance...

    Many may not really know the details, but when they see the total weight at sub 16.5 lbs,... well,
    that by itself is simple enough. Steel has trouble getting there. People know it -- it is simple.

    \Errrrr-adding a pound on the frameset and taking off 10 off your body-not quite the same.

    Who said it was? Again, I'm not going to remove weight from my body and needlessly add some back
    onto the bike. But since you seem to be asking: how different is a pound on the body versus a pound
    on the bike?
